What to mine, the choice of the algorithm
The most profitable mining on the RX 470 Ethash (Etherum), KawPow, BeamHashIII video card. Ethereum Classic is more or less profitable, the rest of Ethash4GB coins are mined on ASICs.
What is better to mine on RX 470 besides Ethereum (ether)? After the departure of Monero, there are almost no profitable tokens left on the kryptonite. It is more or less profitable to mine BitTube , but you will earn more on Ethash . An alternative can be the ProgPowZ and KawPow (RVN) algorithms , but they heat up the cards very much and it is not advisable to switch to them in the hot season. Moreover, the profit is still higher on ETH / ETC.
Experts constantly analyze the most profitable coins, the services they use ( Whattomine, Coincalculator ). Current and latest news is published on the global Bitcointalk forum . There you can find out the newest projects that no one knows about yet.
Dual mining, frequencies for the normal operation of the video card
In the new releases of PhoenixMiner, the developers have added support for the modified ETChash algorithm and ETH / ETC + Zill combined mining.
We set the frequency for the core 1169 and for the memory 2100, with these parameters the card consumes 95 W, Ethereum mining on the video card reaches 26 Mh / s and 450 per decred. Frequencies 1070/2100 reduce power consumption in mining to 70 W, with a hashrate of 25/430, this is the best option for setting up the GPU of a crypto farm.
On the coins of the EquihashZero platform (Vidulum and Zclassic (ZCL)), according to the calculator, the hashrate is not bad for mining, but there are very few pools for work and exchanges.
Often video cards during dual mining can melt 8 pin wires on the power supply. This is due to the colossal high voltage across the core. In order to avoid problems, set the Core Voltage to -100. Detailed settings for dual mining.
BIOS firmware
How to flash an RX 470 video card for mining? To modify the BIOS, the following programs are required:
- ATIWinflash – saves settings and flashes the card.
- SRBPolaris V3-Int – edits bios.
- Atikmdag-patcher – adapts the flashed GPU for Windows and drivers.
Sequencing
- Open Atiwinflash with administrator rights, if there are several cards, select the one you need and press the right Save button to save the original BIOS. It is necessary to make at least two copies, one for editing, another return to the previous settings in case of incorrect operation of the card after reprogramming.
- Open the BIOS in the SRBPolaris utility to change the timings (time delay diagram for correct operation). We look at the manufacturer of the device’s memory. We select the values corresponding to the RAM of the video card.
- We edit the timings and save the modified BIOS. Instead of SRBPolaris , you can use PolarisBiosEditor-master with auto-timing function . But, best of all, grab the timings from here: https://forum.bits.media/index.php?/topic/38510-eth-xmr timing rx470480570580- optimized- timings–configs/
- Click Load image in the Atiwinflash utility , select a new BIOS modification and give the Program command. After flashing, the utility will prompt you to restart your PC. Before rebooting, you must run Atikmdag-patcher , otherwise the system may not detect the video card.
Optimized 470 timings will speed up mining by 25-30% , which is important given the cost of electricity.
When handing over the stitched video cards for warranty repair, the store has the right to refuse repair. Be careful if you decide to change your graphics card settings.
Miners Claymore’s 15 and Phoenix 5.5 know how to modify timings on the fly. In claymore, you need to choose the values -strap and -rxboost , and in the phoenix add the option – mt 1 , or – mt 2 . You will receive the same hash rate as on the modified BIOS and will not risk the warranty.
